Research Abstract

Numerical simulation programs and modeling methods of lightning surge, electric train system and harmonics on distribution system are developed for a stable power supply. New knowledge is obtained from the results which are complementarily calculated by circuit analysis programs and an electro-magnetic field analysis program. Accuracy of the analyzed results and the developed model is confirmed by field test measurements obtained by actual and scale-down systems. The proposed methods have a practical accuracy and their simulation speeds are faster than those of the conventional methods. The results obtained in this study contribute to construct a safe and secure society.
